We compare CFA\(_{\text{fixed}}\)  and CFA\(_{\text{grow}}\)  against one regularization-based approaches (EWCo), one knowledge distillation approaches (LWFA multi-class implementation was put forward to deal with class-incremental learning, as in [1]}), and six memory-based approaches (AGEM, DER, DER++, FDR, GSS, HAL).
